Two studies were conducted to determine the effects of dietary cholesterol (CHO) and cholesterol oxides (COPs) on the development of atherosclerosis and the changes in fatty acid and blood characteristics in rabbits. In the first study, forty male New Zealand white rabbits were divided into 5 groups and fed commercial rabbit chow with no added CHO or COPs, 1 g CHO, 0.9 g CHO + 0.1 g COPs, 0.8 g CHO + 0.2 g COPs, or 0.5 g CHO + 0.5 g COPs per kg diet. In the second study, 24 male New Zealand White rabbits were divided into 3 groups and fed a diet containing 2 g CHO, 1.6 g CHO + 0.4 g COPs, or 1.2 g CHO + 0.8 g COPs per kg diet. All diets induced atherosclerotic lesions in the rabbits' ascending thoracic aorta. The serum CHO and triglyceride levels (p < 0.05) increased significantly with the increased levels of CHO in the diets. Dietary CHO or COPs did not influence high-density lipoprotein CHO levels. The ratio of saturated fatty acid to unsaturated fatty acid increased as the level of dietary CHO and COPs increased.

Despite significant research progress, tumor heterogeneity remains elusive, and its complexity poses a barrier to anticancer drug discovery and cancer treatment. Response to the same drug varies across patients, and the timing of treatment is an important factor in determining prognosis. Therefore, development of patient-specific preclinical models that can predict a patient's drug response within a short period is imperative.

Article Synopsis
- The study focuses on developing safe and cost-effective aqueous electrolytes for improving electrochemical performance, specifically targeting lower salt concentrations and wider electrochemical stable potential windows.
- The authors synthesize porphyrin-based covalent organic polymers (COPs) using a simple method, enhancing their conductivity by wrapping them around multiwall carbon nanotubes.
- Among the different polymers, MWCNT@PTZ-COP shows the best performance in electrochemical applications, achieving high specific capacitance, energy density, and exceptional stability after numerous charge-discharge cycles.

Aims: We evaluated the national and regional trends from 2013 to 2022, in the prevalence of Perthes' disease among adolescent males in South Korea.
Methods: This retrospective, nationwide, population-based study included a total of 3,166,669 Korean adolescent males examined at regional Military Manpower Administration (MMA) offices over ten years. Data from the MMA were retrospectively collected to measure the national and regional prevalence per 100,000 and 95% CI of Perthes' disease according to the year (1 January 2013 to 31 December 2022) and history of pelvic and/or femoral osteotomy in South Korea.
Polycyclic Aromatic Hydrocarbons Mediate the Association between Tobacco Smoking and Alcohol Use Disorder.

Article Synopsis
- - The study explored the link between smoking and alcohol use disorder in 968 male firefighters, focusing on the role of polycyclic aromatic hydrocarbons (PAHs) found in tobacco smoke as potential mediators in this relationship.
- - Results indicated that specific PAH metabolites, particularly 2-naphthol and 2-hydroxyfluorene, were associated with smoking history and significantly mediated the effects of smoking on the risk of developing alcohol use disorder.
- - The findings suggest that exposure to PAHs through smoking may increase the likelihood of addiction issues, highlighting a crucial aspect of how smoking can contribute to alcohol use disorder.

Identity-informative single nucleotide polymorphisms (iiSNPs) are valuable genetic markers for human identification and kinship testing in forensic casework, especially when the quality and quantity of DNA evidence is not suitable for routine short tandem repeat (STR) profiling. This study analysed 105 buccal samples representing the Australian population with European ancestry in order to assign allele frequencies and conduct population genetic analyses for 94 iiSNPs and 20 STRs. The markers were assessed by calculating relevant forensic statistics and testing for deviations from Hardy-Weinberg and linkage equilibrium.
